“…Environmental crazing is accompanied by a continuous stress-induced penetration of the PALE into the as-forming porous structure. When low-molecular-weight or high-molecular-weight compounds are dissolved in the crazing-promoting PALE, they are able to penetrate the fibrillar-porous structure, thus providing the development of a nanocomposite system [18][19][20].…”

Polymer/polymer nanocomposites based on high-density polyethylene (HDPE) and biocompatible polyvinyl alcohol (PVA) were prepared by tensile drawing of HDPE in the PVA solutions via environmental crazing. The mechanism of this phenomenon was described. The HDPE/PVA nanocomposites were studied by the methods of scanning electron microscopy, atomic force microscopy, gravimetry, tensile tests, and their composition, properties, and performance were characterized. The content of PVA in the HDPE/PVA nanocomposites (up to 22 wt.%) was controlled by the tensile strain of HDPE and concentration of PVA in the solution. Depending on the content of PVA, the wettability of the HDPE/PVA nanocomposite (hydrophilic-lipophilic balance) could be varied in a broad interval from 45 to 98°. The modification of HDPE by the biocompatible PVA offers a beneficial avenue for practical applications of the HDPE/PVA composites as biomedical materials, packaging and protective materials, modern textile articles, breathable materials, membranes and sorbents, etc.

“…PEG and PPG as oligomers are widely used in the pharmaceutical and food industry. The use of ecologically safe hydrophilic PEG and PPG as PALEs can promote environmental crazing in “green” mode and provide surface modification and hydrophilization of hydrophobic PP, HDPE, and PET whereas low-molecular-mass and high-molecular-mass compounds are able to penetrate the mesoporous structure of polymers upon crazing [ 26 , 27 , 28 ]. This work presents the study on the potential of environmental crazing as the strategy for the preparation of multicomponent membranes materials that synergetically unite the functional properties of incorporated additives and porous host matrix: membrane performance, vapor permeability, selectivity, hydrophilicity, antibacterial and sensing properties as well high mechanical robustness.…”

This work offers an ecologically friendly and facile approach for the modification of high-tonnage commercial polymers, including polypropylene (PP), high-density polyethylene (HDPE), and poly(ethylene terephthalate) (PET), and preparation of nanocomposite polymeric membranes via incorporation of modifying oligomer hydrophilic additives, such as poly(ethylene glycol) (PEG), poly(propylene glycol) (PPG), polyvinyl alcohol (PVA), and salicylic acid (SA). Structural modification is accomplished via the deformation of polymers in PEG, PPG, and water-ethanol solutions of PVA and SA when mesoporous membranes are loaded with oligomers and target additives. The content of target additives in nanocomposite membranes is controlled by tensile strain, and the level of loading can achieve 35–62 wt.% for PEG and PPG; the content of PVA and SA is controlled by their concentration in the feed solution. This approach allows for the simultaneous incorporation of several additives which are shown to preserve their functional performance in the polymeric membranes and their functionalization. The porosity, morphology, and mechanical characteristics of the prepared membranes were studied. The proposed approach allows an efficient and facile strategy for the surface modification of hydrophobic mesoporous membranes: depending on the nature and content of target additives, their water contact angle can be reduced to 30–65°. Water vapor permeability, gas selectivity, antibacterial, and functional properties of the nanocomposite polymeric membranes were described.
